IMPROVEMENT IN PUMPS.

Specification forming part of Lett/ers Patent No. 49,647, dated July ll, 1865.

To all rrhom it may concern.'

Beit known that I-, Jolis BOLEY, of Baldwinsville, in the county of Onondaga and State of New York, have invented a new and l useful :Improvement in Centrifugal Puuipsi;` andldo hereby declare that the following is a t'ull and exact description thereof, reference being had to the accompanying drawings, anu to the letters o f reference marked thereon, making part of this specification- Figure 1 being a vertical section of the case inclosing the piston, in the plane indicated by the dotted line, Fig. 2, and showing the actuating parts in elevation; Fig. 2, a plan of the case.

Like letters designate corresponding parts inall the figures.

My invention consists in the combination, f with a case provided with an increasing spiral discharge-passage, of a piston having the usual form of wings, with the addition thereto of concave extension-wings D, the whole arranged and operating substantially as herein after described.

The case in which the piston playsis of the ordinary form and construction, being com posed of an upper and lower half, A and B, which are counterparts, fitting together and secured by means of bolts passing through the ears a a, with packing between in the usual manner.

'Ihe shape of the case is eccentric,and itis provided at the proper position with a circular spiral water-discharge passage, dd, commencing at a point at the abutment c where' the piston touches and gradually increasing in diameter around the central circle, till at 1 the eduetion-outlet l1 the eceentricity is equal to the diameter of the passage at that point. A The central portion of the case, or that pory tion in which the piston turns, is made dish ing, as 'represented at b b, and the lower part of said ease has a auge. c, situate iu thek center of the case, extending downward fariI enough to receive the concave extension-wings f l), and a step-bar, E, extends across the botg tom of the case that holds the wings. i

The piston is composed of a center having i radiating wings h h h h, curved longitudinally i in the direction opposite their motion,so as to presenta convex outline on the acting side,l

y well, or any desired height.

i less motive power, and

and concave extension-wings D attached to the lower side of the above-mentioned wings h h h It, and of sutiicieutlength to till and play easily in the tlange c, extending downward from the center of the case. Any desired number of wings may be nsed,four onlybeing represented in the drawings; also, any number of concave extension-wings D maybe used, but equal in number to the large wings above them. Their length is such as to just reach to the tlange c and c, respectively, and to fill the radius of each central circnlar,so that is permitted around them.

but little escape Underneath the piston in the case, extending downward` is a flange, e, of suitable size and depth for the purposc,dcsigned to receive the wings D, which are to till the radius of the angee-and across the bottoni of the flange is a stepvbar. E, and fastened to the ease with slots in the flange, in which is a step4 for the purpose of holding firmly in its place the shaftvG, in which it centers. the wings D is to increase in a very great degree the power, so that a larger volume of water will necessarily be ejected through the spiral discharge-passage H with less motive power.

The -piston is actuated b v a shaft, rests upon and which G, which and is fastened into the step-bar E, extends upward to the top ot' the The shaft is at its top iucased in a metal tube, in which it freely plays. AExtending.from said tube down ward to the case are any number of braces i, (but three are shown in the drawings,) which are fastened firmly to the case.

On the top of the shaft G is a pulley, any desired dimensions or size, around which a belt is intended to run,and the belt attached to any motive power parties may desire, to cause the shaft to revolve.

The small wings D that play in the flange will give the. water the initiator) iuotion necessary to its easy and'continued motion by the large wings above, and therefore will increase the volume of water discharged with will give more fome to thc water and lessen the reaction of the water.
